Abstract

There is provided a control system including a plurality of first apparatuses, and at least one second apparatus that is connected to each of the plurality of first apparatuses. The plurality of first apparatuses each include a conversion unit converting a first voltage supplied from a predetermined power generating apparatus to a second voltage according to a magnitude of the first voltage, and a control unit controlling an on/off state of the conversion unit. The at least one second apparatus includes a power storage unit and a charging control unit controlling charging of the power storage unit. The control unit included in each of the plurality of first apparatuses acquires a value of the first voltage and are operable to carry out control to switch on the conversion unit if the value of the first voltage is larger than a predetermined value.

Claims

1. A control system comprising:

a plurality of first apparatuses; and

at least one second apparatus that is connected to each of the plurality of first apparatuses,

wherein the plurality of first apparatuses each include a conversion unit converting a first voltage supplied from a predetermined power generating apparatus to a second voltage according to a magnitude of the first voltage, and a control unit controlling an on/off state of the conversion unit,

wherein the at least one second apparatus includes a power storage unit and a charging control unit controlling charging of the power storage unit, and

wherein the control unit included in each of the plurality of first apparatuses acquires a value of the first voltage and are operable to carry out control to switch on the conversion unit if the value of the first voltage is larger than a predetermined value.

2. The control system according to claim 1,

wherein the second voltage is supplied from the conversion unit switched on by the control unit to the at least one second apparatus, and

wherein a value of the second voltage determines whether the charging control unit is capable of charging the power storage unit.

3. The control system according to claim 1,

wherein the control unit acquires the value of the first voltage in accordance with a control command supplied from an apparatus different from the plurality of first apparatuses.

4. The control system according to claim 1,

wherein the conversion unit is operable to convert the first voltage in a manner that the second voltage increases when the first voltage increases, and is operable to convert the first voltage in a manner that the second voltage decreases when the first voltage decreases.

5. The control system according to claim 1,

wherein the charging control unit is operable to pull up a charging rate of the power storage unit when the second voltage increases, and is operable to pull down the charging rate of the power storage unit when the second voltage decreases.

6. A control apparatus comprising:

a conversion unit converting a first voltage supplied from a predetermined power generating apparatus to a second voltage according to a magnitude of the first voltage; and

a control unit controlling an on/off state of the conversion unit,

wherein the control unit acquires a value of the first voltage at predetermined timing and is operable to carry out control to switch on the conversion unit if the value of the first voltage is larger than a predetermined value.

7. A method for performing control in a control apparatus, the method comprising:

converting a first voltage supplied from a predetermined power generating apparatus to a second voltage according to a magnitude of the first voltage; and

acquiring a value of the first voltage at predetermined timing and carrying out control to switch on a conversion unit if the value of the first voltage is larger than a predetermined value.
